A= sides²
A = (x+3)²
A = (x + 3) (x + 3)
Next step is to FOIL.
x² + 3x + 3x + 9
x² + 6x + 9
Answer:
30
Step-by-step explanation:
Use substituion.
Substitute -3 for r
(5(-3)(-2)
(-15)(-2)
You answer is 30.
Answer: No
Step-by-step explanation:
Replace x for 5 and -7 separately.
Answer:
Option B
Step-by-step explanation:
Again, another great question! Here we are given the following system of equations, bound by quadrant 1 -
Convert this to slope - intercept form -
Now the graphed solution of this intersects at a shaded region with which there are 3 important point that lie on the border. They are the following -
( 0, 10 ),
( 15, 9 ),
( 17, 0 )
When these point are plugged into the main function f ( x, y ) = 2x + 6y, the point ( 15, 9 ) results in the greatest solution of 84. Thus, it is our maximum point -
<u><em>Option B</em></u>
It’s called the associative law you can add numbers in any order you want
